MicroPoll

The goal of the project is to gather basis for the decision and develop a strategy for the reduction of the entry of micropollutants from urban sewage drainage systems into the waterbodies. The Department Environmental Chemistry participate in

• the selection of indicators for the assessment of the contamination of wastewater and waterbodies with organic micropollutants (Module control of success),
• in the evaluation of the results of the Swiss national material flux model (Module Swiss national material flux model)
• in the evaluation of a full-scale experiment on the ozonation of micropollutants in wastewater at the STP Regensdorf (Module pilot experiment)
• in the evaluation of pilot experiments on the sorption of micropollutants on activated carbon within the wastewater treatment process

The studies are conducted in close cooperation with the department Process Engineering of Eawag.
